Boats aren’t even that expensive everywhere. In America they’re priced as luxury objects for the richest of the rich from what I’ve heard. Sailing as a way of traveling is actually a kinda cheap and rough activity, like camper vans. Not very “rich” stuff at all. My grandparents had a 30 footer and it wasn’t exactly luxurious, definitely camper van vibes. They’d sailed it all over around Europe though.
